Abstract: With such a circuit arrangement, the sampling clock is synchronized to the frame position and the phase of the characters of a received character stream containing a "unique word" at regular intervals. In a digital correlator (1), a crosscorrelation function is generated from a unique word stored therein and from the received, sampled character stream, and a frane detection circuit (2) derives a frame clock (RT1) from those maxima of the crosscorrelation function recurring at intervals of one frame period. To achieve synchronization at any polarity of the received character stream (i.e., even if the tip and ring wires of the subscriber line are interchanged), a second frame detection circuit (3) derives a second frame clock (RT2) from those minima of the crosscorrelation function recurring at intervals of one frame period. A clock selection circuit (8) determines which of the two frame clocks is received within a limited time interval. From this frame clock, control information for representing the phase of the sampling clock (AT) is derived in a phase synchronization circuit (10).

Inventor: MATSON STEPHEN L
IPC: B01D19/00
Filed: 1984-03-07
Granted: 1990-12-06
Abstract: In a process for the recovery and reuse of the heat contained in the gas/vapor overhead mixture from a stripping column (1) in which a noncondensable gas is stripped from a liquid solution by contacting the solution with a hot vapor such as steam, the steam or other vapor in the overhead mixture is separated from the noncondensable gas or gases by preferentially passing the vapor through a semipermeable membrane (2). The water or other condensable vapor is then compressed and either reinjected at the bottom of the stripping column (2) or condensed in the column reboiler (4), thus permitting its reuse in the stripping process. If the compressed vapor is reinjected into the stripping column, it serves as the stripping medium itself. If the compressed vapor is condensed in the column reboiler (4), its latent heat of vaporization is thereby recovered and used to generate the required stripping vapor by boiling the solution being stripped.
